wont go to swipe to unlock screen

[Android Central Question]

when I press the power or home button it opens my phone to whatever I was doing before, instead of going to my lock screen. if it sits long enough itll lock, but I want it to go to the lockscreen without opening completely, if that makes sense lol

Welcome to Android Central! Which phone? Look in your System Settings for the Automatically Lock option. It might be in the Display or Security menu. Change the interval there; there should also be an option to automatically lock the screen when you turn the screen off with the Power button.
